Fig. 5: Estimation of water bulk modulus.
From: Ultrasound propagation in water-sorbing carbon xerogel
a Schematic illustration of the spatial distribution of the fluid-filled pores during the uniform saturation and the patchy saturation. b The effective bulk modulus of the xerogel sample, obtained from ultrasonic measurements and estimated from Gassmann, GW, and GH approximations (indigo dashed line with an empty marker: extrapolation of experimental data to find the bulk modulus at full saturation).
